Product Name

Name:/span>CTAB-modified Au nanorods (ethanol solvent)

Product Overview

CTAB modified gold nanorods (AuNRs) are a special type of nanomaterial in ethanol solvent. In ethanol, CTAB modified gold nanorods can form a uniform dispersion, which helps to maintain the dispersibility and stability of the nanorods. The modification of CTAB helps to protect gold nanorods from oxidation and aggregation, thereby improving their stability in different chemical environments.

^{Product Features}

Surfactant Stability: CTAB (Hexadecyltrimethylammonium bromide), as a surfactant, forms a stable dispersion system through the negative charge interaction between its cationic head group and the surface of gold nanorods. Solubility in ethanol: Ethanol is a polar solvent that can dissolve CTAB modified gold nanorods, forming a uniform nanosuspension. Optical properties: Gold nanorods have unique optical absorption and scattering properties, especially the surface plasmon resonance (SPR) effect, which gives them special optical responses in the visible and near-infrared regions. Size and shape dependence: The SPR peak position of gold nanorods is closely related to their size and shape, and can be regulated by adjusting these parameters. Chemical stability: CTAB modification helps protect gold nanorods from oxidation and aggregation, improving their stability in different chemical environments. Catalytic activity: The surface plasmon effect of gold nanorods can enhance their catalytic performance, making them highly active in certain chemical reactions. Environmental sensitivity: The optical properties of gold nanorods are sensitive to environmental conditions such as pH, temperature, and ionic strength, which provides possibilities for environmental monitoring and sensor development. The Convenience of Ethanol Solvent: Ethanol, as a widely used solvent, is volatile and easy to handle and remove, which provides convenience for the subsequent processing and application of gold nanorods.

^{Application Fields}

Biosensing: The surface plasmon resonance properties of gold nanorods give them potential applications in the construction of biosensors for detecting trace molecules. Biological imaging: Gold nanorods have strong scattering in the near-infrared band and can be used as contrast agents for biological imaging, especially in light scattering imaging. Catalysis: Gold nanorods can serve as catalysts or catalyst carriers to improve the efficiency of catalytic reactions, especially under conditions of light irradiation. Sensors: The surface enhanced Raman scattering (SERS) effect of gold nanorods makes them applicable in the field of sensors for detecting biomolecules, ions, etc. Optical components: Gold nanorods can be used to manufacture near-infrared filters, nonlinear optical components, polarizers, etc. Information storage: The wavelength tunability and polarization dependence of gold nanorods can be used to prepare high-capacity information storage devices. Anti counterfeiting: The optical response of gold nanorods in the near-infrared band makes them high-end anti-counterfeiting materials. Surface modification: CTAB micelles are used to modify the surface of citrate capped gold nanoparticles to achieve different surface charges and chemical properties.
